Remarks. New record for Lesvos Island, Greece. In addition, B. rugulosa is known to live in old galls of Andricus kollari (Hartig, 1843) ( Hymenoptera, Cynipidae, Cynipini), as a parasitoid of tiny inquiline lepidopteran species (Bouček, 1951; Lotfalizadeh et al., 2012). As such, A. insanus is considered a new host gall for B. rugulosa .
